ABSTRACT
The present investigation titled, “Evaluation of Marigold genotypes for growth and flowering” was carried out at the experimental farm of Department of Floriculture and Landscape Architecture, Dr. Y.S. Parmar, University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh during August, 2021 to March, 2022. The experiment was laid out in a Randomized Block Design with three replications. Eleven genotypes of marigold were evaluated in this experiment. Significant variations were observed among all the genotypes for all the parameters under study. Maximum plant height (96.80 cm), number of primary branches (11.20), number of secondary branches (44.74), maximum flower size (5.78 cm), flower yield per plant (802.00 g), flowering duration (95.14 days) and benefit-cost ratio was observed in the genotype ‘Punjab Gainda-1’. The genotype ‘Bidhan Kali Gainda’ was observed to have maximum plant spread (72.17 cm). Minimum days taken to flower bud appearance and days to flowering were observed in the genotype ‘Pusa Deep’ (43.67 and 55.75 days, respectively). Maximum number of flowers per plant was observed in the genotype ‘Bidhan Kali Gainda’ (393.47). It was concluded that the genotype ‘Punjab Gainda-1’, BM-4’ and ‘Pusa Narangi Gainda’ were promising for loose flower production.
